Previous studies indicate that the southward migration through Oregon lasts about two months (Herzing and Mate 1984). However, 90% of the whales migrated past Yaquina Head between December 19 and January 23. The northward migration through Oregon is divided in two phases. Phase A, which comprises adults without calves, begins during the last week of February with a peak in mid-March.
Humpback whales are migratory animals, traveling up to. 3,000 miles from their feeding grounds in the cold waters of. the Polar regions, to their breeding grounds in the warmer. waters of tropical regions. TEACHER NOTE: Ask students to point out on the map provided where the Polar region is located as well as the tropical region.
